Table 3 Risk factors for intraoperative ventilation management: simple logistic regression analysis.
Factor | AE n = 27 | Non-AE n = 108 | OR | 95%CI | P value |
|---|---|---|---|---|---|
Mean airway pressure during mechanical ventilation, cmH2O, mean (SD) | 9.2 (1.8) | 8.3 (1.7) | 1.36 | 1.04–1.79 | 0.026 |
PEEP, cmH2O, mean (SD) | 3.8 (1.3) | 4.0 (1.4) | 0.89 | 0.66–1.21 | 0.47 |
Incidence of hyperoxic exposure (FIO2 > 0.8 for > 1 min), n (%) | 17 (63) | 79 (73) | 0.62 | 0.26–1.52 | 0.30 |
Mean inspiratory oxygen, %, mean (SD) | 51.5 (16.4) | 48.2 (14.8) | 1.01 | 0.99–1.04 | 0.31 |
Duration of mechanical ventilation, min, mean (SD) | 334 (200) | 298 (186) | 1.0 | 1.0–1.0 | 0.37 |
